某國以風景秀麗、歷史名勝著稱。還有很多牧場和豬場。在這種情況下，飼養(yǎng)者對改善豬場通風十分重視。除了排氣扇之外，他還把舊窗扇換成了自然通風的電動開窗器。

開窗器的工程師把舊的窗玻璃換成了安裝好的電動開窗器。電動開窗器保持自然光的感應能力，還增加了通風尺寸。百葉窗已安裝在較高的地方，因此，工程師還安裝了線性致動器作為電動開窗器。所有者可以使用中央控制面板操作所有窗口，而不是手動打開每個窗口。

直線執(zhí)行器具有IP 54額定保護。防止灰塵和水噴霧。它可以安裝在半露天的地方。另外，當百葉窗開度達到90度時，其通風和日照的尺寸增大。因此，通風與照明的能力是建筑的主要要求。人們通常選擇電動開窗器而不是向外打開窗戶或滑動窗戶。

在的農場里，有3只豬崽。每個豬舍都安裝了大約10個電動開窗器。百葉HETCEC安裝電動開窗器控制器的每一豬舍?？刂破骺煽刂?0個電動開窗器。內置的遠程控制功能，讓業(yè)主操作所有窗口更容易用遙控器，而不是手動打開每個窗口。

Yeoncheon gun of Korea is famous for beautiful scenery and historical site. There're also many pasture and piggery. In this case, the owner pay much attention on improving ventilation of piggery. Besides the exhaust fan, he had changed the old casement window to electric louver for natural ventilation.

The engineer of Louver Hitec removed the old casement windows replace with installed electric louvers. The electric louver retain the ability of inducing natural light, but also increase the ventilation dimension. The louvers was been installed in higher place, therefore, the engineer also installed KST-A01 linear actuators as electric window opener. The owner can operate all window with central control panel instead of opening every window manually.

linear actuators are with IP 54 rated protection. Prevent from dust and water-spray. It's could be installed at semi-outdoor place. Additionally, when the leaves of louvers are opening to 90 degrees, it majorly increase the dimension of ventilation and sunshine. Therefore, if the ability of ventilation and lighting is the main requirement of building. People usually choose louvers instead of outward opening windows or sliding windows.   

In Sung Hyun's farm, there are 3 piggeries. And each piggery has been installed about 10 electric louvers. Louver Hitec installed KST-B18-R electric window opener controller for every piggery. Eash controller can control 10 electric louvers. The built-in remote control function let the owner operate all windows easier with remote controller instead of open each windows manually.
